Last year I bought about 6 containers (30 servings each) of Gundry Prebiothrive and had one scoop in a glass of water each morning for several months. I did not notice any difference either plus or minus. But after several months I started having huge amounts of gas which I'd never had in my life (I'm 63), and also some constipation and diarrhea. These were all very unusual and the only thing I was doing differently from the past was taking the Gundry product which I stopped, and will not talk again. The gas and other issues have continued for several months after I stopped taking the product.
Bottom Line: No, I would not recommend this to a friend
